FIELD

The present invention is directed to a battery, for example, a rechargeable battery such as a rechargeable lithium ion battery for use in a vehicle such as a motorcycle, road bike, dirt bike, trike, scooter. Moped, automobile, truck, plane, boat, jet ski, recreation vehicle (RV), all-terrain vehicle (ATV), four wheeler, and other applications (e.g. electrical back-up unit).

BACKGROUND

Typically, most vehicle batteries in use today are lead acid batteries. However, more recently, lithium ion batteries or other rechargeable battery chemistries are being developed for use in vehicles and other applications.

There exists a need for improved batteries.

SUMMARY

The rechargeable battery according to the present invention, for example, is a rechargeable lithium ion battery for use in a vehicle. The rechargeable battery according to the present can also be used with other battery chemistries.

The rechargeable battery comprises a casing having a positive terminal, a negative terminal, and one or more internal cells contained within the battery casing. For example, the rechargeable battery comprises multiple cells (e.g. six cells) connected together in series providing or connected to a positive terminal and negative terminal. For example, the individual battery cells each have a positive tab and negative tab so that the positive tab of one cell can be connected (e.g. soldered, fastened, or otherwise connected) to the negative tab of the next cell to provide a series arrangement between the cells.

The battery casing, for example, can comprise an upper section, middle section, and lower section connected or assembled together. For example, the battery cells can be installed within the battery casing prior to assembly. Further, for example, the upper section, middle section, and lower section can be structured and arranged to connect together (e.g. configured to snap fit together).

The upper section of the battery casing, for example, can be fitted with a positive terminal and a negative terminal made of electrically conductive material (e.g. lead or lead composite metal material). For example, an insert molded type positive terminal and an insert molded type negative terminal is molded into the battery casing. For example, the insert molded type positive terminal and insert molded type negative terminal are molded in spaced apart upper wall portions of the casing.

The casing, for example, is molded (e.g. injection molded, vacuum molded) plastic material (e.g. polyethylene terephthalate, polypropylene). For example, the casing is made of a single layer of material or multiple layers of material (e.g. multiple layers of different plastic materials). Further, the insert molded type positive terminal and insert molded type negative terminal can be insert injection molding to the wall of the battery casing during injection molding of the battery casing.

The insert molded type positive terminal and insert molded type negative terminal can be structured and arranged to connect, respectively, directly to a positive battery cable and a negative battery cable. For example, the insert molded type positive terminal and insert molded type negative terminal can be provided with one or more threaded holes so that a connecting bolt can connect each battery cable to each insert molded type terminal. Alternatively, or in addition, the insert molded type positive terminal and insert molded type negative terminal are each provided with a protrusion or ear having a through hole to allow a bolt and nut to connect each battery cable to each insert molded type terminal.

As another alternative, a positive external terminal and a negative external terminal are connected, respectively, to the insert molded type positive terminal and insert molded type negative terminal. For example, the external terminals are provided with one or more through holes to allow a bolt to connect the respective external terminal to the insert molded type terminal. The external terminals can be provided with one or more threaded holes to allow a bolt to connect the externals terminals to the respective positive battery cable and negative battery cable.

The battery can be structured and arranged to cooperate with one or more battery trays to change the effective height of the battery. For example, the bottom section of the battery casing can be configured to nest within an upper receiver of a battery tray. The battery tray can have different heights. Further, a lower end of the battery tray can be configured to nest within the upper receiver of another battery tray to provide a stacked arrangement of battery trays. For example, a plurality of same height or different height battery trays can be stacked to tailor a final assembled height of the battery with battery trays for a particular battery installation on a vehicle.
